Re: o Re: sequence of octets bug in Orbit when running server as root?t

[Claude Beazley <cbeazley hgmp mrc ac uk>]

I've tried different sizes of octet sequence and it works for smaller 
sequences under root, but falls down on the larger ones. So it appears that 
when running as root, Orbit2 places an upper limit on the size of an octet 
sequence. The server running as normal doesn't seem to have this upper limit. 
Is this a feature or bug?
